Votes or likes to answers?

I am not sure if it is here where I can make this question, but here I go. I am practically new to this forum, in some forums that I have been part of there is a "like" button or a "vote" button, or points for the people who answer your questions, I haven't seen any of them in here, am I missing them or just there isn't. I feel sometimes rude because I can't do anything else but thank the person who answered my question.
